[Nasal septum perforation and bevacizumab]

A 52-year-old woman, with a metastatic breast cancer, presented with a nasal septum perforation while receiving a treatment combining paclitaxel and bevacizumab. This is the fifth reported case of nasal septum perforation probably related to an anti-angiogenic therapy. A literature review and a discussion concerning the different causes of nasal septum perforation were performed.

[Choriocarcinoma with pulmonary metastasis: diagnosis and treatment]

INTRODUCTION

Choriocarcinoma is a rare tumour which results from the anarchic proliferation of a gonadic or extra gonadic germinal cell.

CASE REPORT

A 45 year old pre menopausal woman of African origin presented with a persistent cough and deterioration of general status. The chest X-ray revealed a cavitated mass of the right upper lobe. Other lesions were associated (liver, kidney and scalp). Choriocarcinoma, suspected in the presence of an elevated ssHCG without a gravid uterus, was confirmed by biopsy excision of a haemorrhagic cutaneous lesion of the scalp. Despite the poor prognosis methotrexate based chemotherapy resulted in control of the disease and a good remission.

[What are the new therapeutic strategies in metastatic colorectal cancer including biotherapies?]

Colorectal cancer remains one of the major causes of cancer death. Recent identification of new molecular targets led to the development of novel agents directed against growth factor receptors or key factors of angiogenesis. Recent phase III trials demonstrated a significant clinical benefit with bevacizumab, a VEGF inhibitor, and with EGFR-inhibitors, namely cetuximab and panitumumab. In this article we review the diverse treatment options combining cytotoxic and targeted therapies available for patients with metastatic colorectal cancer.

Efficacy of FOLFIRI-3 (irinotecan D1,D3 combined with LV5-FU) or other irinotecan-based regimens in oxaliplatin-pretreated metastatic colorectal cancer in the GERCOR OPTIMOX1 study

BACKGROUND

Second-line irinotecan-based chemotherapy is commonly used in metastatic colorectal cancers after first-line oxaliplatin-based chemotherapy. No standard schedule of irinotecan has been established in this situation.

PATIENTS AND METHODS

Metastatic colorectal cancer patients included in the OPTIMOX1 phase III study received first-line oxaliplatin-based chemotherapy (FOLFOX). No second line was defined in the protocol, but data concerning second line were prospectively registered. Inclusion criterion was patients receiving an irinotecan-based second-line chemotherapy. Second-line progression-free survival (PFS) and tumor response were evaluated according to type of irinotecan-based regimen administered.

RESULTS

A total of 342 patients received irinotecan-based chemotherapy as second-line chemotherapy: FOLFIRI-3 [n = 109, irinotecan 100 mg/m(2) days 1 and 3 combined with leucovorin (LV) 400 mg/m(2) day 1 and 46-h continuous 5-fluorouracil (5-FU) 2000 mg/m(2)], FOLFIRI-1 (n = 112, irinotecan 180 mg/m(2) day 1 combined with LV 400 mg/m(2) day 1, 5-FU bolus 400 mg/m(2) and 46-h continuous 5-FU 2400 mg/m(2)) and other various irinotecan-based regimens (n = 121). Median second-line PFS was 3.0 months (FOLFIRI-3: 3.7 months; FOLFIRI-1: 3.0 months; other regimens: 2.3 months). In multivariate analysis, FOLFIRI-3 regimen (relative risk 0.43, 95% confidence interval 0.28-0.68, P = 0.0003) and lactate deshydrogenase level at inclusion (P = 0.0006) in OPTIMOX1 were associated with a longer second-line PFS.

CONCLUSION

In unselected patients pretreated with oxaliplatin, PFS in second line appeared to be improved by FOLFIRI-3 regimen.
